Structure | Typical Standard Specifications of KPR Main Section

This system is composed of two parts - the Main Section (the Solvent Concentrating Part) and the Disposal Section.
The Main Section is centered around the KPR rotor which has superior adsorption-desorption qualities. This is combined with the Disposal Section composed of a direct combustion incinerator, or a catalytic oxidizer, or solvent recovery apparatus depending upon your requirements.
The system comprises, in effect, a total pollution control program.
The heart of the system is the KPR rotor which is fabricated with Toyobo's activated carbon fiber (K-Filter), with its incomparably excellent and efficient adsorption-desorption properties.

The Main Section
Figures 1-1 and Figures 2 provide a schematic representation of the KPR rotor with a disk, or with a cylinder. Figure 1-2 shows you the distinctive honeycombed K-Filter adsorbent. Adsorption and desorption are attained continuously by dividing areas of the rotor into blocks, one for adsorption and the other for desorption, and by rotating the rotor. The solvent-laden air and the purged hot air ,both flow along the tubular routes of the blocks. The hydrocarbon ingredients in the solvent regenerated continuously in the desorption block.
The volume of hot air being purged for desorption is but fractions of several tens, compared to that of the solvent-laden air. As a result, the concentration of solvent in this purged gas is increased tremendously.
Drastic reductions in size are achieved by high air velocities(2-3m/sec.) based upon superior adsorption abilities of the K-Filter, and by a lower pressure drop caused by designing the air flow to run parallel to the adsorbent.

Three Types of the KPR System
The Toyobo KPR Solvent Gas Treatment System comes in three types. They are all designed to meet your needs and are determined by the type of the disposal equipment being applied.
